Be it known that I, HENRY B. HEMPHILL,

a citizen of the United States, residing at Stonefort, in the county of Saline and State of Illinois, have invented new and useful Improvements in Ventilating Attachments for Stovepipes, of which the following is a speci-i` readily connected with the outer end of the` stovepipe andv the opening in the chimney.

The inventionconsists in certainnovel features and in the arrangement and construction of parts hereinafter described by which the increased efficiency referred to is obtained in view of thewell-known limitations in the use of the chimney-draft for such purposes.

In order that my invention may be fully understood, I will proceed to describe it withv reference to the accompanying drawings, in which Figurel is a side elevation of myim proved Ventilating attachment, showing it connecting 4a stovepipe with a chimney. Fig.` 2 is a vertical longitudinal section of the ventilat-` ing attachment, and Fig. 3 is a front elevation thereof.

Referring to the drawings, 1 is aivertical' stovepipe provided with a damper 2 and having connected to its `upper-end an elbow 3, which is ordinarily connected with alhori- `zontal pipe-section inserted in the opening 5a of a chimney 6. 1 In the place of this horizontal pipe-sectionI locate my Ventilating attachment. This-attachment is constructed with a horizontal pipe-section 7 having a damper 8 adjacent to its outer end and a thimventilator elbow.

9, whereby it is secured to the horizontal l pipe-section. This thimble is of` approxi- `mately one-half the diameter of the horizontal pipe-section. Connected with this thimgble so as to extend at a right angle to the E horizontal pipe-section is a coupling pipe-section 10. This coupling pipe-section extends `vertically from the upper side of the horizon- 'tal `pipe-section, so as to be located between `the latter and a point adjacent to the ceiling of the room. i

11 is a damper-shaft pivotally arranged .yacross Vthe coupling-section and havingsuitably mounted and secured thereon a damper 12, whereby the draft through the ventilator may be regulated. To the projecting end of the shaft is fixeda cross-bar or damper-lever 14, having perforations 15a at its respective ends, wherein areloosely secured rings 16, to which are dependingly secured chains, cords, or rods 17, provided with handles 18, whereby the damper may be operated as desired.

Detachably secured to the upper end of the coupling pipe-section is "an elbow 13, formed at its free end with a Haring liange 13' and mounted on the coupling-section, so as to be turned thereon and having one portion parallel with the ceiling to take in "air from diierent directions from the room as may be convenientanddesired. Withintheentrance to the elbow is iitteda circular frame 19, provided with a flaring annular ange 19a at its outer end adapted to lodge and seat against the base portion of the flaring ange of the Diametrically across the circular frame are secured parallel bars a, b, provided at their middles `with,bearing-apertures 21, in which is journaled a shaft 22, on which is mounted a fag-wheel 23, whereby the :force of the draft through the ventilator may be indicated. On the inner bar b may be provided a lug 24 to prevent the shaft extending too far inward in its bearings.

It is well known that ventilators of this type have employed a pipe attached to the stovethe air of the room at that point where it is the most vitiated; but such ventilators, opening as they do to the ceiling and directly above the stove, take the air from that section and in such a gradual manner as not to bring about immediate results and often no substantial result at all, owing to the draft whichcan be utilized for this purpose being very slight and its force being dissipated on the air immediately surrounding lthe Ventilator-entrance without causing an effective circulation of the air in the room. From the foregoing description it will be seen that not only has the choking effect of the ceiling been removed by the employment of an extension paralleling the ceiling and opening to the wall opposite to the chimney-wall, thus giving direction and movelnentrto the air in the farthest portions of the room, but also making immediate the ventilation of certain portions of the room most needing ventilation by turning the horizontal pipe to assume the desired direction. By the direction or control of the draft in the above mannerin the upper air of the room the results have been found to be effective even when the draft is slight on account of the requirements of the stove for its utilization.

A great advantage in the construction of the Ventilating attachment is the fact that it can be readily fitted in the place of and substituted for the ordinary elevated pipesec tion, which extends horizontally from the stovepipe to the chimney, and is entirely out 'ver centrally pivoted therewith, and means at the opposite ends of the lever for operating the damper, of a movable elbow mounted on the coupling and having one portion parallel with the ceiling and at the open free end a Haring flange, a circular frame provided with a Haring ange which is adapted to be connected to the flaring fiange on the free end of the elbow, and spaced-apart parallel bars located diametrically across the circular frame having central bearing-apertures in which is journaled a shaft havinga fan mounted thereon between said spaced-apart parallel bars, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY B. HEMPHILL.
